The operation "known as brushing an; lows that of jackin and consists in b11'1s'h-- ing the'fibe'rs" or nap raised by the jacking operation for the purpose of cleaning, pol ishing;and-straightening out the fibers and also 0t" thickening! the nap ped surfaco by briuging out fibers which may have been partially-loosened by thejackingoperation: This brushing operationis" usually pen termed in hot water or other solution and in orderto be effective should besuch that the fibers are brushed ina plurality- 0f"di' rections in 1 order thoroughly to' clean and polish them on all sidesi V Theoperati'on knowni'as sizing is, in a sense, the opposite of th jaokingoperation and is forthe purpose of consolidating the hodyand inereasin'g the intetlooking of the" S0 fibers;

Theirolls 19 and 21am; connected-inn :15:

pairs by gears 93. each roll 19 being connected to the roll 21 beneath and to the left thereof, as shown in Fig. 3. Preferably and as herein'shown the rolls 521 are greater in number by one than the rolls 19, the roll 19 at the right of the series as shown in Figs. 1 and 3 being connected with both of the adjacent rolls below the same. Thegears 23 of'the rolls of one set are formed of a sufficient width to permit relative reciprocation of the two sets of rolls transversely of the machine, as hereinafter more fully described. Preferably, and in order to econoniize space, the gears 23 connecting the rolls of the several pairs are arranged on the shafts 24 of said rolls alternately at opposite sides of the frame. The shafts 24 of the upper and lower rolls are journaled in boxes 31 and32 preferably adjustably secured by bolts 38 and 34 to the upper and lower frames 20 and 22, respectively.

The character of the surfaces of the rolls 19 and'21 is in accordance with the character of the operation for which the machine is used. For the jacking operation said rolls are provided with suitable projections formmg carding surfaces of a well known char? acter, as by covering the same with the usual carding cloth. For thc'brushing operation brushing rolls of ordinary type are employed. For the sizing operation there may be employed rolls of theform shown in Fig. 10, said rolls being each composed of a series of disks 25 of Wood mounted on the shaft 2 with the grain transverse to the axis of said shaft and clamped thereon, between fixed andloose collars 27 and'28 respectively, by means of a nut 26. Preferably, however, and as shown in Fig. 11, a metallic sizing roll composed of some non-corroding metal, such as brass or bronze and provided with a roughened surface 1s employed, such a roll being considered of material advantage over the usual wooden roll which in time is likely to splinter and cause the splinters to enter the hat body, thereby damaging the same.

In order to permit certain of the rolls, particularly the brushing rolls, to be easily and quickly removed and replaced, said rolls are preferably formed in two semi-cylindrical sections, as shown in Fig. 6, which are assembled about the correspondin shaft 24 and held in place thereon by a col ar 29 (see Fig. 7 slipped over the reduced ends 30 of said sections and secured inplace by pins passing through suitable openings in said collar, end portions30, and shaft 24.

' (see Fig. 1). denotes a drivingshaft journaled in the machine frame, provided with the usual belt pulleys 36, and connected with the roll shafts 24 by suitable transmission devices. As shown the shaft 35 is provided with sprockets 37 and 38 connected by chains 39 and 4:0 with sprockets 41 and 42 011 the shafts 24 of the first two upper rolls 19, counting from the left in Figs. 1 to 3. Each of said last named shafts 24 is provided with a sprocket 43 connected by a chain 44 with the sprocket 45 on the second shaft 24 of the series toward the right. The arrangement of these transmission devices or driving connections is such as to provide for driving the several rolls at relative velocities determined by thecharacter of the operations to be performed, as will now be explained.

In the brushing operation it is desirable that the pairs of rolls have a progressively accelerated movement, this being the arrangement shownin Fig. 1, from which it will be seen that the second roll 19 counting from the right will be rotated at a slightly greater speed than the first, the third at a greater speed than the second, the fourth at a greater speed that the third and so on through the series. In operation the hat bodies are fed into the machine from the apron 17 at the right in Fig. 3 and between the first pair of rolls, pass through the entire series of rolls, and are discharged upon the apron 17 at the left. As the second and third pairs of rolls are each rotated faster than the preceding pair, one pair of rolls is in effect brushing the nap forward while the other pair isbrushing it backward, this for the reason that, while bot-h pairs of rolls are turning forward, as the forward pair is turning relatively fast the, slower movement of the first pair gives the effect of brushing the nap backward. Simultaneously with this brushing of the nap forward and backward the nap is brushed in each direction-transversely by a relativedateral movement of the rolls of i the upper and lower set respectively as hereinafter described.

For the operation of jacking transmission devices are preferably provided which will cause all of the rolls to be rotated at the same speed, so that the small points of. the carding or other jacking covering gently withdraw the ends of the fibers from the hat body. While it would be possible to employ the machine for jacking operations with rolls having a progressively accelerated movement, as above described in connection with the brushing operation, this would cause a more severe treatment of the body, breaking and completely withdrawing a con-- siderable number of fibers.

In employing the machine for sizing operations a series of transmission devices providing for progressively retarded movement of the rolls is employed. In order to produce a sizing effect, a squeezing or pressing together of the fibers is necessary. If, therefore, the rolls be operated in such a manner that each succeeding pair of rolls rotates at a slightly less speed than each preceding pair, there will be a tendency for one set of driving connections for rotating all of said rolls at a unlform speed. Such an arrange- 1110I1l3 is illustrated in Fig. 12 wherein 96 denotes a series of sizing rolls of progressively decreasing diameter from the right orfront end of the machine to the left or rear end tln-u'eof. R will be seen that while the rolls 96 are all driven at the same angular velocity their peripheral velocities will progressively diminish from the front to the rear ofthe machine, thereby producing the same sizing effect as in the case of a series of rolls of equal diameter driven at a progressively diminished speed.

46 denotes upright supporting arms pivoted at their lower ends upon studs 4.7 projecting from the machine frame adjacent the bottom thereof and at their upper ends upon pins 48 carried by the upper frame 20. The arms 46 are arranged in pairs at opposite ends of the machine, whereby the frame 20 is supported .for substantially horizontal movement transversely of .the machine or parallel to the axes of the rolls. The arms 46 are preferably formed in two sections connected by sleeves 49, whereby the length of said arms may be adjusted. As shown, said sleeves 49, are in adjustable threaded engagement with the upper sections of said arms and form at their lower ends sockets which receive the lower nut-breaded sections of said arms, the upper ends of said lower sections preferably engaging stop bins 50 carried by said sleeves. The sleeves 4:9 are preferably split and are clamped in adj osted position upon the sections of the arms 4-6 by means of bolts 95. With this arrangement, by loosening the lower bolts the upper sections of the arms 46, together with the sleeve-s49, may be readily separated from the lower sections of said arms, there by-perinitting the upper frame 20 to be raised in order to afford convenient access to the rolls carried thereby and to the lower frame 22. The capacity for independent adjustment of the arms 46 by means of the sleeves 40 provides not only for the adjustment of the frame 20 toward and from the frame 22, but also for the relative angular adjustment of said frames. thereby permitting the use of rolls of different dian'ictcrs, as above described in connection with the sizing opcratioin'and as shown in Fig. 12.

51' dcnoics lugs depending from the upper frame 20 and carrying bearing members 52 which are. held in adjusted position in said lugs by means of stop screws 53 and which engage the auxiliary frame 55 for the purpose of guiding the roll frame 20 in its lateral movements.

from the machine.

56 denotes brackets secured to the lower portions of the auxiliary frame 55 and formed at their upper sides with short raeeways 57 (Fig. 5) extending transversely of the machine and in which are located rolltially parallel to the direction of movement of the frame 20. l-Vhen desired for purposes of obtaining convenient access to the lower rolls 21, or otherwise, and after the upper frame 20 has been raised, as above explained, the lower frame 22 may be readily lifted from the rollers 58 and removed Certain of the rollers 58, preferably two of each set, are provided with side flanges 60 (Fig. 12) which engage the outer faces of the raceways 57 and bean iug plates 59, thereby serving to hold the frame 22 against movement longitudinally of the machine and guiding its lateral movement.

For imparting the lateral movements above referred to to the frames 20 and 22 the following mechanism is provided, reference being had to Figs. 1 to 5: 61 denotes a shaft mounted in journals 62 secured to the main frame of the machine, said shaft being connected, as by bevel gears 63, with the driving shaft 35. (,4 denotes a crank disk secured to the shaft 61 and having a transverse guideway 65 in which is adjustably mounted a block (if) carrying a crank pin 67. By adjusting the block 66 in the guideway 05 the throw of the crank pin 67 may be varied according to requirements. 68 denotes a link pivoted at one end to the crank pin 67 and at the other, by-means of a pin 69, to an arm 70 secured to a rock shaft 71 journaled in brackets or ears 72 carried by the frame uprights 15. The arm 70 is preferably of the curved or gooseneck form shown in Figs. 4 and 5 in order to extend over the edge of the tank 19. 73 denotes levers secured at their central portions to the shaft 71 and having arms extending upwardlyand downwardly from said shaft. 7% denotes links pivoted at 75 to thenpper arms of the lovers 73 and at 76 to cars 77 projecting from the upper frame 20. 78 denotes links pivoted at 79 to the lower arms of the lovers 73 and at 80 to cars R'l on the; lower frame 22. The pivots 75, 7(3, 79 and 80 preferably comprise removable pins, whereby either of the roll frames may be disconnected from the reciprocating mecha- The links 7-l and 78 are preferably arranged in pairs at opposite sides of the levers 73 and ears 77 and 81. The shaft 61, crank disk. (54. and crank pm 67. when rotated, operate, through the link 68 and arm 70, to rock the shaft 71, and through the levers 73 and links 74 and 78 to reciprocate the frames 20 and in opposite directions, thereby producing a relative lateral movement of the rolls l9 and2l in a direction parallel to their length. The amplitude of the reciprocation of the frames 20 and 22 may be adjusted by adjusting the block 66 in its-guide (35. The links 74 are provided with arms 82- which extend over the upper members of the frame 20 and carry stop screws vVhen the frame 21 is raised for the purpose of obtaining access to either set of rolls said frame will first turn about the pivots 76 independently of the links 74 for a slight distance until the top members thereof engage the stop screws 83, after which said frame and links will turn in unison about the pivots 75, thereby completely separating the upper and lower frames and disengaging the gears A modified construction is illustrated in Figs. 8 and 9. In accordance with this modification the links -74 and 78 are adjuslably connected with the arms of the levers 73, such connection being provided in the construction shown by forming each of the arms of the levers 73 with a series of openings 97 arranged in arcs of circles concentric respectively with the pivots 76 and 80; The removable pins constituting the pivots 75 and 79 are adapted to be engaged with any of v the openings 97 of the correspondingseries.

By thus adjusting the points of connection of the links 74 and 78'with the levers 73 the amount of lateral movement given to each of the frames 20 and 22 at each operation of the rock shaft 71 may be varied. Preferably the arrangement will be such as to provide for an adjustment of the parts in which either one or both of the frames will remain stationary. As above explained the amount of movement given to both frames may be adjusted by means of the block (36, while the adjustment of the connections of said frames with the levers 73 provides for varying the movement of either frame with respect to or independently of the other. In the construction last described the arms 82 are formed on separate yokes 84- pivoted on the pins 76 and l'iaving each a series of openings 85 adapted to receive a removable pin 86 which also passes through suitably disposed openinns in the corresponding links 74:. The openings 8:: of each yoke 84 are arranged in the arc of a circle concentric with the corresponding pivot 76 andare so disposed as to permit the connection of the yoke 84 with the links 7-1 in such amanncrthat, irrespective of the connection of said links with the lever 73, the stop screw 83 will be held in relatively close proximity to the correspond ing member of the frame 20.

87 denotes beams extending longitudinally of the machine outsidethe uprights l5 and upon which the tank 18 is supported. The

beams 87 normally rest upon removable pins 88 which are inserted in suitably disposed openings 1n the uprights 15.

- 89 denotes stirrups embracing the beams 87 and carrying stop screws 90 upon which and lowered into and out of its normal position, as shown in full lines in Figs. 2 and 3. Said tank is guided in its vertical movements bythe engagement of the beams 87 with the uprights 15 and by engagement of the walls of said tank with the frame members 15. 54. and 55. The tank is, of course, normally supported on the pins 88 but may be lowered at will into the position shown in dotted lines in Fig. 3. or into any intermediate position. for the purpose of cleaning the tank. to afford easy access thereto in case a hat body passing through the machine should slip between the rolls into said tank, and also for the purpose of ad justing the depth of submersion of the rolls in the fluid contained in the tank.

The operations of the various parts of the machine have been fully explained in the course of the foregoing description, but the operation of the complete machine may be reviewed as follows: The tank 18., which is normally held in the position shown, is filled with a suitable liquid, usually boiling water, to av depth which will cover the. lower rolls 21 and partly cover the upper rolls 19, so that the various operations are all performed while the hat bodies are immersed in said liquid. Said hat bodies are fed to the machine from the right end thereof in any position, it being wholly immaterial whether they are fed in tip first, or edge first, or brim first. After passing through the machine the bodies are closed or folded in a different position and are passed through again, the operation being repeated as many times as mav be desirable.

\Vhcn used as a jacking machine suitable jacking rollers may be employed together with driving connections whereby said rollers are all, rotated at the same speed. As the hat bodies pass between said rolls the small points of the cardingor other jacking covering on the rolls enter gently into the bodies and draw gently out as the body leaves the bodies are immersed in boiling water thehbers are softened, less liable to break, and

may be drawn out of union with the body more 'easily. If the mechanism be so adjusted as to give to the roll frames a slight sideu'ise reciprocation during the jacking operation, such movement will have a certain sizinp or tightening effect upon the body, offsetting the opeuii'ig tendency caused by drawing some of the fibers out of union. For the brushing operation suitable brushing rolls are employed and driven at a progressivel y accelerated speed which, as above explained, tends to brush the fibers both forwardly and backwardly. The roll frame reciprocating mechanism is usually so Mljusted as to give both of said frames a maximum throw, thereby causing a continual lateral movement of the rolls upon one another and brushing the fibers laterally in both directions, so that said fibers are brushed in four different ways. By passing a hat body through the machine several times in different ways it will be seen that the fibers may be thoroughly'brushed in substantially every direction. The lateral reciprocation of the rolls during the brushing operation also has a certain sizing or tighteningeffect upon the hat body. It has been found in some grades of hats that the brushing and tightening of the body is accomplished better when the machine is so adjusted that only one set of rolls is reciprocated, and. by the preferred construction above described it will be seen that such adjustment may readily be effected.

When used a sizing machine alone suitable sizing rolls will be employed together with driving: connections whereby said rolls will be given a progressively diminishing peripheral velocity. this result being accomplished, as above explained, either by employing a set of rolls all of the same diameter and driven at a progressively reduced speed or by employing a series of rolls of progressively reduced diameter all driven at the same speed. In addition to the sizing or crowding effect upon the hat body produced by such a set of rolls, as above explained, in the direction in which said bodyis moving through the machine, there is also a sizing effect in the direction transverse thereto due to the opposite reciprocation of the upper and lower sets of rolls, and in order to equalize the sizing in one direction with that in the other the amplitude of reciprocation of the roll frames is suitably adjusted by adjusting the position of the slide 66 in the guide 65. This sizing operation is also greatly facilltalcd and the results greatly improved by being performed While the hat bodies are immersed in boiling Water.
